Abstract: An array substrate and a manufacturing method thereof, a display panel, and a display device are provided. The array substrate includes a bonding region and a non-bonding region, and further includes: a rigid substrate, in the non-bonding region, a driving circuit layer, in the non-bonding region; a light-emitting diode layer, on a side of the driving circuit layer away from the rigid substrate; a flexible base layer, m the bonding region and on the same side of the rigid substrate as the driving circuit layer; and a bonding wire layer, on a side of the flexible base layer away from the rigid substrate. The bonding wire layer and the flexible base layer is capable of being bent along an edge of the rigid substrate to a side of the rigid substrate away from the driving circuit layer.

Abstract: A driving substrate includes a base substrate. The base substrate has a display region and a peripheral region, and the peripheral region includes a bonding region between the display region and a first side face of the base substrate. The driving substrate further includes a plurality of first pads spaced apart from each other, which are disposed in the bonding region of the base substrate. A first side face of each first pad is flush with the first side face of the base substrate. A thickness of the first pad is approximately in a range from 0.5 microns to 2 microns.
